This article shows that including offsets in climatechange legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,

In the CalNex 2010 study outlined here, NOAA researchers are studying several issues at the heart of the coupled air quality and climatechange problems.
It makes an important contribution to the scientific understanding we have of the role of aviation for climatechange—an understanding decision-makers and politicians may need on the way to achieving the goals of the Paris Agreement. This new study is based on a thorough review of a decade of research on aviation emissions.
Europe must dramatically cut its water consumption and use water more efficiently if it is to avoid the worst impacts of water shortage, the European Environment Agency ( EEA ) warns in a new report, “Water resources across Europe—confronting water scarcity and drought”. “
Nearly all electric utilities claim climatechange is threatening power outages, higher costs and changes in usage as demand for power grows in response to new requirements such as electric vehicles, increased cooling during warmer summer months and rapid urbanization, according to a new Acclimatise global report, backed by IBM.
The study, from the University of Washington, the University of California Santa Barbara and federal scientists, is published in Nature ClimateChange. The new paper focuses specifically on what this atmospheric circulation means for Arctic sea ice in September, when the ocean reaches its maximum area of open water.
In an interview with the Los Angeles Times , US Secretary of Energy Steven Chu said that water shortages resulting from worst case scenarios of climatechange could eliminate agriculture in California and place its cities in jeopardy. I don’t think the American public has gripped in its gut what could happen,” he said.
Widespread climate-related impacts are occurring now in the US and are expected to increase. A product of the interagency US Global Change Research Program, the 190-page report was commissioned in 2007 and completed this spring. It is clear that climatechange is happening now.

An understanding of the rate of carbon release is necessary to estimate the strength of positive feedback to climatechange, a likely consequence of permafrost thaw. Scientists have been cautious about estimating average sea level rise this century in part because of complex processes within ice sheets. Permafrost.
